LW+ admixture
Supports water resistance, workability and mix performance depending on the product.
01 Inside
Admixture · dosage · water resistance
LW+ is mixed into concrete, mortar or plaster. It improves water resistance and workability inside the mix.
Adding LW+ does not mean every other waterproofing layer can disappear. It works inside the mix; a membrane or joint treatment does a different job.
02 Boundary
With LW+, an integral liquid waterproofing admixture is added at a specified dosage. Without it, correctly designed concrete can still perform well when properly protected.
Supports water resistance, workability and mix performance depending on the product.
Forms a dedicated barrier where exposure and detailing demand it.
Treats places where construction breaks the continuity of the material.
Specified dosage, correct mixing and curing remain essential.
03 Spec
The issue is not “below LW+.” It is whether the concrete and waterproofing strategy are complete without it.
Which product, at what dosage, in which mix?
04 Check
An admixture, surface barrier and joint detail work in different places.
