TRI-GEL

n BBA certified rising damp treatment

n Fast, clean application

n Ready to use, water based gel

n No need for electric pump on site

n Cartridge gun or compression pump application

n Guaranteed effective

A cost effective and guaranteed method of treating rising

damp in brick, stone or block walls. Tri-Gel is a water

based and water soluble thixotropic gel which diffuses

naturally into damp substrates and reacts to form a

water repellent silicone resin network. This network is

permeable to water vapour which means the walls can

“breathe” and dry out naturally. Injected using a cartridge

gun or hand operated compression pump,

Tri-Gel eliminates the need for electric pumps on site.

Installation:Tri-Gel is injected into 12mm diameter holes, drilled

horizontally into the chosen mortar bed at 100 –

120mm centres or at the perp joint, mortar bed junction

(brickwork). See below:

Holes should be drilled to within 20 – 40 mm of the far

face of the wall being treated. Treatment can be carried

out from one or both sides of the wall as appropriate and

convenient. Cavity walls would normally be treated from

both sides. The holes should be filled to within

10 – 20 mm of the front face of the wall and capped with

a plug of sand and cement mortar incorporating Trimix 1

or with a DPC wall plug. Spillages should be washed away

with water before they dry.

n No pump cleaning required between jobs

A unique silicone emulsion cream for injection into

brickwork etc. for the control of rising dampness.

Tri-Cream can be used in all types of masonry without

the use of high pressure equipment. The cream is

delivered by hand pressure from a simple displacement

pump and injector lance into a series of holes drilled into

the mortar course. Migrating rapidly into the masonry

pores, the injection cream reverts to a liquid phase and

polysiloxanes are formed in situ.

Installation:Tri-Cream is injected into 12mm diameter holes drilled

horizontally in the mortar bed at centres no greater

than 120mm. The depth of hole is dependant upon wall

thickness – refer to product data sheet. Each hole should

be back filled fully with Tri-Cream to within 1cm of the

surface. When treating cavity walls from one side, make

certain that the holes in each leaf are filled.

Note:When installing Triject Rapid, Triject 2 or Triject 3, allow 10-15% increase in consumption for constructions such as random stone walls or rubble in-fill where fluid loss may occur.

Installation of all Triton’s chemical damp proof courses should, wherever possible, follow the guidelines laid down in BS 6576:2005 “Code of Practice for diagnosis of rising damp in walls of buildings and installation of chemical damp-proof courses” and the BWPDA Code of Practice: “The Installation of Remedial Damp-Proof Courses in Masonry Walls”.


TRITON INJECTION MORTAR (T. I .M)

n Prevents rising damp in walls

n Especially suitable for thick or random

rubble filled walls

n Odourless

n Gives off no toxic vapours

A one component injection mortar designed to stop rising

damp in brickwork, blockwork, random rubble filled walls

and all types of masonry. T.I.M should be injected into

pre-drilled holes using a hand caulking gun.

Triton Injection Mortar is based on Ordinary Portland

Cement, selected fine quartz aggregates and active

waterproofing chemicals. It activates due to a chemical

reaction between moisture in the structures and

waterproofing chemicals in the mortar which forms a

crystalline growth that blocks the capillaries, pores and

fine cracks in the mortar joints.

Preparation/Installation:Holes should be drilled using 19 – 22 mm drill bits at

overall spacings of 110mm and at an angle of depression

of about 30°, finishing in a mortar bed at the level of the

proposed DPC. In solid walls up to 460mm thick drilling

from one side to the thickness of the wall (and at the 30°

angle) should result in a hole terminating 50mm or so

from the far side. It may occasionally be advantageous

to drill from both sides ie random stonework with rubble

infill or thick walls. Drilling should stop just over half way

through the wall, the holes being at staggered centres of

110mm. Prior to application, all holes should be flushed

out with water to remove any dust. T.I.M should always be

injected into damp holes.

In walls less than 120mm thick, rather than drill holes,

the mortar bed should be raked out at the desired level

to between one third and one half its depth.

Mix T.I.M at the ratio of two to three parts water by five

parts powder by volume. Add the water to the powder.

Mix thoroughly until a smooth cream is achieved, using

a mechanical whisk if possible. Do not mix more mortar

than can be used in 20 minutes.

Using a hand caulking gun, insert the nozzle into the

holes to the full depth and backfill slowly, stopping

approximately 50mm from the top of each hole. Top up

to this level if necessary. Holes should then be plugged

with 3:1 washed sharp sand:cement using Trimix 1

Render Additive.

Replastering:Replastering using a salt retardant render additive such

as Trimix 1 is essential if hygroscopic salts and residual

moisture are to be successfully held back.

TRIMOTIC

ELECTRO-OSMOTIC DAMP PROOFING SYSTEM

n Chemical free

n Suitable for virtually any type of wall

n Eligible for insurance backed guarantees

n Minimal running costs

Trimotic is a chemical-free damp proofing system that

utilises the principle of Electro-Osmosis. Electro-Osmosis

occurs when an electrical potential is applied across a

damp porous material which causes a force to be exerted

on the water which then moves towards the cathode (earth).

The Trimotic system involves inserting platinum coated

titanium wire anodes into the wall at regular intervals.

These anodes (which are joined together by plain

titanium wire) are placed around the building in a ring

main-like configuration. One end is connected to a low

voltage power supply and the circuit is completed at

the other end by an earthing rod (cathode) driven into

the ground to a level below that of the anodes and

at a distance of at least two metres away from the

nearest anode. The completed and operational system

then provides the electric potential, which stops the

rising damp and allows the wall to dry out. Removal

and replacement of salt contaminated or damaged

internal plastering is carried out as usual and to the

normal specifications used when replastering after the

insertion of a chemical damp proof course.

THE THREE KEY COMPONENTS OF THE TRIMOTIC ELECTRO-OSMOTIC SYSTEM

Power unitThe simple and robust power unit

plugs into a 13 amp socket. The plug

connected to the unit’s output lead

simply fits into a socket fitted to the

titanium wire of the installed system.

Power delivery from the unit adjusts

automatically to the degree of

dampness in the wall thus ensuring

the best possible results.

AnodesThe anodes are supplied spliced

into pure titanium wire. Each anode

consists of a titanium wire substrate

coated with platinum. The platinum

is very resistant to oxidisation and is

used to ensure excellent long term

electrical conductivity into the wall.

Earthing RodsThe earthing rods complete the

circuit. The electrical potential

created by the power unit is between

the anodes and earthing rod(s),

therefore it is important to achieve a

good earth contact.

WALL WITHOUT PROTECTION ELECTRO-OSMOTIC SYSTEM INSTALLED


PRINCIPLES OF INSTALLATION

1) Before a Trimotic Electro-Osmotic system can

be considered a full survey of the property should

be carried out. Floor levels inside and out, wall

construction type(s), floor construction etc., should

be determined alongside the diagnosis of dampness

itself. Once rising damp has been correctly diagnosed

attention can be turned to the practical considerations

of where power units and earth rods can be positioned

and what the best route for the installation of the

anodes might be.

2) Installation of the anodes can be from the outside

or the inside of the building, in either case the internal

rendering will almost certainly need to be removed due

to salt contamination. If not, at the very least skirting

boards will need to be removed to allow access to the

base of the wall when internal installation is carried out.

3) The anodes are inserted into the wall via holes

drilled from a mortar bed down at an angle (varying

from 10° to 30°) The titanium wire between the anodes

is placed into a 20mm chase or groove cut into the

mortar bed.

THE PROCESS TYPICALLY PROCEEDS AS FOLLOWS:

c) Form the first anode into a 'J' shape ensuring that all the platinized wire will be inside the wall.

a) Cut a groove 20mm deep into mortar bed.

b) Drill into wall from mortar bed to at least 1/3 thickness of wall.

f) Wet the anode holes with a watering can and then fill with a cement and water slurry.

d) Run the wire along the wall and push the anode into the back of the hole.

e) Pull the wire taught, mark and drill the wall, form the second anode and fit into the hole.

i) Spurs can be created for return walls etc. by joining anode wire using the crimps. A continuous loop of wire is not required.

g) Point up the groove containing the titanium wire.

h) Doorways and other openings are bridged using plain titanium wire attached to the anode containing wire using the titanium crimps.

The titanium wire should be considered to be live (although at a very low, safe voltage as far as people and animals are concerned) and should not come into contact with any other metal such as central heating pipes, electrical boxes or wiring etc.

Insulating sleeving or tape should be used to isolate vulnerable wire.

Warning labels are supplied for attachment to the wire for display in prominent places.

j) Place an earth rod into the ground at a lower level than the lowest anode.

k) Connect the earth rod and power unit(s) (one power unit is sufficient for 100 anodes) and switch on.


TRITON RENOVATING PLASTER

n For plastering most traditional background materials during renovations

n �Particularly suitable following the installation of a new damp proof course

Triton Renovating Plaster is a lightweight, cementitious

plaster which has been developed to control dampness

passing through plastered walls of old properties. Triton

Renovating Plaster is designed to have similar properties

to a 1:1:6 cement:lime:sand plastering mortar but with

Perlite lightweight aggregate replacing the sand. Man-

made fibres are incorporated into the mix to control

shrinkage and improve flexural strength.

Installation:Once the old plaster has been removed and the DPC

installed, Triton Renovating Plaster is applied before the

finishing coat to hold back residual moisture and salts.

To be used in accordance with recommendations in

BS 5492. Triton Renovating Plaster is compatible with

most building materials. The waterproofing additive and

Lime content minimises efflorescence and rusting of

metal lathing and conduits, at the same time controlling

pattern staining and mould growth.

TYPICAL DPC INSTALLATION FORHIGHER EXTERNAL GROUND LEVEL


TRIMIX 1


n Improves workability of mix

n Delivers water and salt resistance to mix

n Suitable for internal and external use

A water and salt resistant additive for cement mortars

which is designed to improve the workability of the mix

and, after curing, imparts water repellency and salt

resistance. Trimix 1 also reduces the amount of water

required to provide a workable mix and hence produces

a more dense render. Trimix 1 is suitable for use with

mortars and renders for internal and external use but

is particularly recommended for use in internal cement

rendering (replastering) of walls which have received a

damp proof course.

Installation:One litre of Trimix 1 should be diluted with 25 litres

of water. The diluted Trimix should then be used as

gauging water without further dilution. In replastering

internal walls affected by rising damp, the recommended

specification is that Trimix 1 should be added to the

first (10mm) coat of cement mortar only. This should be

followed by a second coat without the addition of Trimix

1 which should be applied after the first coat has set but

before it has dried. The finishing coat should be a porous

lightweight plaster skim applied after the cement render

coats are fully cured.

Specification:In accordance with NBS Specification ‘J10 Cementitious

Mortar Tanking/Damp Proofing 120 Cement: Sand Mortar

with Proprietary Waterproof Admixture’.

TRI-REND

n Improves workability of mix

n Suitable for internal and external use

n Delivers water and salt resistance to mix

A waterproofing, salt inhibiting and plasticizing additive

for sand and cement renders and mortars. Tri-Rend

improves workability to the mix and, after curing,

imparts water repellency and salt resistance. Tri-Rend

is recommended for use in mortars used for internal

cement rendering (replastering) of walls affected by

rising dampness.

Tri-Rend is an alkali metal soap of aliphatic fatty acids

dissolved in water. The concentrate is alkaline

(about pH11).

Installation:One litre of Tri-Rend should be diluted with water to make

40 litres. The diluted Tri-Rend should then be used as

gauging water without further dilution. In replastering

internal walls affected by rising damp, the recommended

specification is for Tri-Rend to be added to the first

(10mm) coat of cement mortar only. This should be

followed by a second coat without the addition of

Tri-Rend which should be applied after the first coat has

set but before it has dried. The finishing coat should be a

porous lightweight plaster skim applied after the cement

render coats are fully cured.

Specification:In accordance with NBS Specification ‘J10 Cementitious
