s Don’ts 1. Do not use a protection screed over
Preprufe® Plus The membrane isdesigned to bond to structural concrete.
2. Do not use as pond or tank liner.3. Do not use Preprufe® Plus for installation
in concrete infilled hollow block wallconstruction. Preprufe® Plus is designedfor use with reinforced concrete designedfor a maximum crack width of 0.6mm.
4. Avoid curved shapes for permanentformwork and blinding otherwiseextensive cutting and folding of thePreprufe® Plus will be necessary. Angularformwork will generally be easier foruse with Preprufe® Plus.
5. Do not try to bond the selvedge if thePreprufe® Plus is wet. A hot air gun canbe used to dry the selvedge.
6. Do not use staples to fix Preprufe® Plus totemporary formwork.
7. Do not allow water to pond beneath thePreprufe® Plus prior to concreting - can liftto the membrane and damage the joints.
8. Do not ‘mix & match’ Grace waterproofingmembranes with membranes from othermanufacturers except with prioragreement with both companies.
9. Do not allow the vibrator to come intocontact with Preprufe® Plus - can damagethe membrane.
10. Do not apply Shotcrete to Preprufe® Plus.
Do’s1. Use flush fixings to fix Preprufe® Plus to permanent formwork.2. Place flush fixings through the Preprufe® Plus selvedge to enable them to be covered by the next overlapping sheet.3. Where fixings are made to secure vertical Preprufe® Plus to temporary formwork, 40 mm clout nails should be used, 20 mm being left exposed to provide an anchor for the nail during striking of the formwork.4. Seal fixings with 2 layers of Preprufe® tape where fixings have been placed through the membrane into blinding but not overlapped.5. Firm fold Preprufe® Plus at 90° changes in direction to allow maximum contact with the substrate.6. Extend the Preprufe® Plus beyond the starter bars rather than the edge of the stop-end formwork to ensure easy overlapping of the adjacent bay Preprufe® Plus. 7. Stop the Preprufe® Plus minimum 50 mm below top of concrete surface on temporary (removable) formwork.8. Use Preprufe® Tape at all overlaps including the adhesive selvedge when the ambient application temperature is expected to fall below 0°C.9. Seal ‘Fish Mouth’ openings i.e. where the overlapping Preprufe® Plus has not stuck to the layer beneath should be sealed, with Preprufe® Tape.10. Air lance debris away immediately prior to concreting unless there has been a heavy build up of mud on the Preprufe® Plus in which case use a high pressure water hose and air lance.11. Repair damage to the Preprufe® Plus membrane before concreting.12. Remove surplus water from the excavation to be concreted.13. Check all the release liner has been removed before concreting.14. Remove grout spillage on Preprufe® Plus as it can locally inhibit the bond of fresh concrete placed on it.15. Ensure that correct concreting and vibrating practices are observed during concreting.16. Concrete with pfa, additives and admixtures can be used with Preprufe® Plus.17. Wait until the concrete strength is 10 N/mm2 before striking the formwork.
