Multi-performance support for home foundations

You can reduce vibration and protect valuable homes by installing SANDAM Base Isolation Rubber between the groundsill and foundation of wooden structures. The product increases ventilation efficiency up to 200%, compared to conventional products.

Seismic Isolation

This product reduces building vibration caused by earthquake and maintains the level of earthquake resistance the house had when it was newly built.
You can reduce vibration and protect valuable homes by installing SANDAM Base Isolation Rubber between the groundsill and foundation of wooden structures. SANDAM Base Isolation Rubber reduces vibration at maximum of 30 to 50% compared with non-use (* In-house evaluation).
The joint rigidity and earthquake resistance of new buildings deteriorate due to the repetition of small vibrations and impacts over years. SANDAM Base Isolation Rubber supports absorption of such vibration and impact.

Vibration Proofing

This product is effective against vibration caused by traffic and/or construction.
In addition to reducing earthquake vibration, SANDAM Base Isolation Rubber is effective in reducing vibration caused by traffic and/or construction. Further, its vibration/impact absorbency achieved good results in measurements of vibration caused by (1) passing express trains, (2) passing large trucks and (3) construction through lambda.

Ventilation

The product increases ventilation efficiency up to 200%.
SANDAM Base Isolation Rubber provides ventilation slits all around buildings to enable more air than ever to pass through to ensure regular ventilation under the floor and prevent stagnation. The product is especially effective for corners, where moisture tends to stay, and reduces the risk of mold and corrosion. In addition, the product increases ventilation efficiency up to 200%., compared to conventional products.

Durability

We protect the life of homes in humid Japan from the floor up.
This product improves the durability of the foundation, because it does not require the cutting of ventilation holes, and also because its soft rubber characteristics help reduce the load on the concrete base of buildings. In addition, this product can prevent wooden material decay, including lumber girders, because it isolates the groundsill from the moist concrete foundation.
The use of SANDAM Base Isolation Rubber leads to the extended lifetime of your precious home by taking advantage of the traditional principle of natural ventilation to protect wooden Japanese homes built in humid circumstances from the floor up.
