Precast

Precasting concrete is an alternative to cast in place concrete. Precasting structures allows for better quality control of the concrete often times produced indoors for optimal curing conditions. Precast assemblies in the field are very efficient often returning projects to service in less than half the time of cast in place. Precast structures however have to be built in segments due to weight and scope. A couple examples are concrete pipe and manhole riser sections. These jointed segments need to be treated with joint sealants and waterproofing wrap treatments. Our Line of Blackhawk Hawk-Seal joint sealant, Blackhawk 5401 Pipe Joint Mastic and Blackhawk Hawk-Wrap external joint wrap are essential components to create a watertight connection.

  • Hawk-Seal comprised of butyl rubber, demonstrates excellent ability to perform over a wide range of installation conditions as it exhibits minimal hardening or softening.
  • Blackhawk 5401 Pipe Joint Mastic is a versatile trowel grade material that can be used on a wide range of joint sizes making the need for different sized material unnecessary.
  • Blackhawk Hawk-Wrap is the same butyl rubber material laminated to a HDPE film to add puncture and tear resistance during back fill or joint deflection. Coatings both internally and externallyon precast structures are also often needed. On internal surfaces carrying sanitary waste our products such as Novocoat SC1100 Concrete Primer and Novocoat SP2000 protect the concrete surface from hydrogen sulfide gas and microbial induced corrosion (MIC). External coatings are often specified to add damp proofing to the surface. Our Blackhawk 5011 winter grade and Blackhawk 5012 summer grade products are a solvent based asphalt coating known for their ease of use, storage and application. Ertech offers 2110 as an asphalt emulsion damp proofing widely known for environmentally friendly low VOC’s.
