Sika® Corporation's Retail Group Launches Revolutionary Post Fix

LYNDHURST, N.J. -- Sika Corporation recently launched Sika® Post Fix, a two-part, pre-proportioned polyurethane resin which when mixed produces expanding foam. It has been specifically formulated and packaged to provide a lightweight, mix-in-the-bag, fast-setting and high-strength backfill for wooden, PVC and steel in-ground posts. The Sika Post Fix formulation is based on Sika's proven foam technology and is designed for the easy, convenient and quick support of many types of posts, including wood, PVC, metal or concrete posts.

Sika Post Fix is ideal for the novice or pro installer and is super easy to apply. One bag replaces two 50 lb. bags of concrete mix, and there are no special tools or water required. The installation is simple and saves the customer time and money as it sets in just three minutes, reducing the time required to brace or support the post when compared to traditional concrete mixes. It hardens completely in just two hours and any excess material cured above the surface of the ground can be cut away with a sharp knife before covering with top soil.

Sika Post Fix has a unique chemical formulation that does not harm the soil or surrounding environment. Once mixed and in a foam state, Sika Post Fix is inert and will not leach into the soil. Sika Post Fix will be available through select The Home Depot stores and other select retailers.
