A slurry applied treatment used in the control of lateral penetration of water in walls below ground level.
Aquastop Tanking Slurry is not sulphate resisting.Application
The surfaces to be treated must be totally free from dust, dirt, loose material, plaster, bitumen, oil, paint etc. In particularly difficult circumstances sand blasting may be the most effective means of providing a clean surface for treatment.
Where Aquastop Tanking is to be used in conjunction with water repellent chemicals for dampcoursing, contamination of the surfaces with water repellent prior to tanking must be avoided.
Perished areas of brickwork or concrete should be cut out, down to solid structure, and any iron or steel rods cut back to as least 2cm below the surface. Uneven surfaces should be levelled with a 3:1 sand:sulphate resisting Portland cement mix which should be allowed to cure before applying Aquastop Tanking.Backing Render:
In cellars and other areas of high hydrostatic pressure the surface should be prepared as indicated above. The mortar joints should be raked out and, if necessary, the surface hacked to provide a sound mechanical key for the backing render.
The backing render should be 3:1, washed sharp sand:sulphate resisting Portland cement (SRPC) applied to a minimum thickness of 10mm. Allow to cure for 24 hours before applying Aquastop Tanking.Mixing:
Aquastop Tanking is supplied as a powder and must be mixed with water to form a slurry to use at the rate of 7.5-8.0 litres of water to each 25 kg bag.
Once mixed the slurry will remain workable for approximately 80 mins. Do not attempt to prolong usable time by adding further water.
