TBS Services, a Building Consultant from New Jersey reached out to Sika and was looking for a waterproofing solution that could be installed on the existing gutters at the Planetarium of the Rowan University. The gutters were leaking and the Consultant needed a solution with minimal disruption for the building owner. Sikalastic RoofPro 20 year system, a fully reinforced and fully adhered liquid applied waterproofing system has been evaluated by the Consultant as most suitable solution.

Sikalastic RoofPro systems and it's unique Sika Reemat Premium fiberglass reinforcement confirm perfectly to all kinds of shapes, and allowed the contractor to install a 100 % seamless waterproofing system in the gutters. The Sikalastic-641 Lo-VOC resin with reduced solvent and minimal odor allowed the contractor to install the system without any precautionary measures in terms of odor mitigation. The contractor was able to finish the job on time, and highlighted the fact that Sikalastic-641 Lo-VOC is rain resistant immediately after application, and he was less dependent on the weather with his construction schedule.
