Cementitious capillary crystalline waterproof material waterproof coating for basement roof waterproofing

Features :

1) Non toxic and tasteless, no contamination to environment.

2) Can be applied by brushing or spraying on concrete surface when mixing with water; dry powder can also be applied to

moist or green concrete.

3) Permanent; waterproofing resistance remain intact even after surface damage.

4) Able to self-cure fine cracks.

5) Easy to apply.

Construction technology:

1. Clean up the debris and mud mortar on the cardinal plane of waterproof coating , repair serious uneven concrete base.
2. Clean up the oil and eradicate the debris of cement concrete structure surface, then washing with water, construction brushing waterproof material on wet surface.

3. If there are serious leakage detected, we should first adopt plugging material construction, then use the material, to ensure the engineering quality.

4. The ratio of water cement is 0.3-0.4:1, the dosage is 1.4-1.7 kg/m², thickness is 1.0 mm(±0.05mm)as the standard.

• roller painting

The material according to the amount of 1.4-1.7kg/m² uniform with the rolling brush roll the base surface after processing.

• dry scatter process

1. Construction immediately after the concrete pouring dense compacted flat. The required amount evenlysprinkled on concrete surface, timely sleeking compaction. After the final set check if there is a bad construct andrepair in time.
2. In the case of exposure, watering for maintenance. Pay attention to spray evenly, do not cut corners.

Scope of application:

Widely used in tunnels, dams, reservoirs, power stations, nuclear power plants, cooling towers, underground railways,

overpass,bridges, underground continuous wall, airport runway, pile headpile foundation, purification tank for liquid waste,

water reservoir, industrial and civil buildingroofing, basement, toilet bathroom’s waterproof construction, and concrete

building facilities all the ills of the concrete structure repair plugging.

Matters need attention:

1.Normal construction, construction should not be below zero centigrade and rain, fog, windsand and other harsh conditions.

2.Mixed with water, conserve water in drinking water was the best, inappropriate use of not cleancontaminated water.

3.The construction must be carried out in the concrete structure or solid cement mortar base surface, not directly used for the

ash layer surface, the base surface should be clean and no dust, old firm,dust dirt, and other debris,to provide a fully open

capillary system,is conducive to thepenetration of the product and the formation of crystals.

4.All ofconcrete is need to coating the products , should carefully check whether there are structural defects, such as rod hole

template,cracks, honeycomb shaped inferior surface, potholes, unsmoothconstruction joint interface , should repair chisel,

cleaning, caulking, reinforcing, leveling, and undertake large waterproof construction.

5.When construct sanitary, pipe joints shouldmake special processing, it can along the tube wall and the base surface,

chisel 10 mm deep V groove to sealing, then coat the base waterproof coating.

6.To make sure that the coating thickness and construction recommended dosage.In construction of brushing method, if the size is too thin, uneven stirring, adding water two times and so on, are easy to cause the base powder or shell phenomenon.

7.Such as the concrete members need to backfill , after construction of 36 hours can fill in wet soil, but within 7 days can

not backfill dry soil, to prevent absorbing waterof the waterproof coating .

Transportation and storage :

The products should avoid moisture, rain, fog, transport should prevent collisions, pay attention to the storage life is one year.
