Foam concrete for blocking water in mining project

Grouting to stop water for preventing groundwater is an important technology. Currently, prevent water glass slurry and cement slurry is the main material. The advantage is low cost, sources. But after hardening, it is easy to shrink, can produce a small gap. Wash water, will become a bigger gap, so the effect is not ideal.
It we use foam concrete as the material for blocking water, the effect will be much better. Foam concrete doesn’t shrink and is no deformable, it will increase the flow paths to achieve better effect of blocking water.
We can supply high performance foam concrete machine “according to the application of the company. More information about our products, contact us. Email ID:
