DSM-DS is a highly resilient, double sided, silicone faced, precompressed sealant that has proved over the years the ability to solve difficult joint sealing problems where other systems have failed or are not suitable. It is ideal for new installations as well as expansion joint repair or retrofit jobs. It is especially useful in unique locations such as a topping slab seal in split slab assemblies, waste water facilities, tunnel walls and ceilings, planter walls, and interior side of foundation floors and walls which all benefit from its construction and performance*.
The dual-sided silicone facing allows DSM-DS to be installed from either the negative side or positive side. DSM-DS is adhered to the substrate walls with an epoxy adhesive which combines with the foam’s backpressure to be held in place. When accessible during installation, field-applied silicone sealant bands seal voids in the substrate and seal the edges of the bellows to the joint faces.
