DSM-DS System

About this product

Dual-sided silicone bellows seals from both sides of joint. 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. *NOTE: For structures with waterproofing, backfilled or blindside, EMSEAL suggests the use of BG system for most applications. The BG system is designed to tie into the waterproof system. The BG multi-cell gland and dual-level side flashing flanges provide for stress-free, redundant integration into the below-grade waterproofing membrane to form an integrated, secure watertight seal. Features: Non-Invasive Anchoring Continuity of Seal through changes in plane and direction Ability to handle variations in joint size Ideal for new and retrofit installations ADA Compliant
