Machine Base Grouting: Micro-Concrete Pours and Epoxy Bedding for Equipment

Avatar for TargetTarget
Machine base grouting fills the gap between a concrete foundation and the steel base of a pump, compressor, generator or crane rail. It looks like a small item on the drawings. Yet a poor grout layer leaves voids under the plate, loose anchor bolts and a machine that slowly loses alignment. In Egyptian factories, pump stations and workshops, we often ... Read More

Facade Movement Joint Sealing with Polyurethane Sealant: Sizing and Steps

As a result, panels, blockwork and frames move constantly. A sealant that cannot follow this movement cracks or peels, and rain finds its way in. This guide covers sealant ... Read More

However, asphalt alone does not keep water out. In fact, water seeps through the surfacing, reaches the deck and attacks the steel. This guide reviews the main system options, from torch-applied membranes to sprayed ... Read More
