NATCEM CWG Flowable Grout – 25kg

NATCEM CWG Grout is an environmentally friendly, flowable and waterproof grout with specially recovered aggregates. The product is suitable for a range of applications and starts to set after 35 minutes and is totally set in 45.

Applications:

• Waterproof grouting
• Grouting during repairs to sewers
• Controlled soil stabilisation grouting
• Void filling
• Work around the sea
• Wherever pollution or chemical attack is likely

Properties:

• Excellent adhesion
• Low shrinkage
• Excellent resistance to pure water & sulphated water
• Excellent resistance to aggressive chemicals
• Very good cohesion & mixing
• Fine compact surface
• No curing membrane necessary
• Can be used in wet conditions
• Can be used under water
• Controlled setting
• Fine particle size for greater penetration
• Set down to zero
• Can be injected in to artesian water bearing strata, as it contains no material to leach out into the aquifer

Preparation:

Do not use on frozen or over-heated substrates (0° – 30°).

Setting Times:

NATCEM CWG Grout is designed to commence setting at 35 minutes and finish setting at 45 minutes at 20°C. The set can be accelerated by using warm water. In hot temperatures, the set will be faster and can be slowed by using cold water or NATCEM SETTING RETARDER (see separate product data sheet).

Yield:

Generally, 1 x 25kg bag of CWG Grout mixed with 4 litres of water will produce 14 litres of finished grout.

Placing:

After mixing, apply the material as quickly as possible using traditional tools. Once setting has started DO NOT attempt to remix or to smooth the surface. This will cause the mechanical properties, in particular strength and adhesion to be lost.

Mixing:

For optimum results, mix using conventional mixing machines.
