Embedded below is a crack and curtain grouting video demo I recently recorded.  For those not familiar with me, my name is Charlie Lerman. I'm the Director of Technical Services for the Leak Seal Division at Alchemy-Spetec (and I'm also known as the Grout Geek). I have been involved in a wide variety of grouting jobs from dams to tunneling, municipal to sewer system work, residential, commercial, and industrial.

Prior to joining the Alchemy-Spetec team, I was with the Navy in the submarine and recruiting services. I have 20 years of construction experience – I was with a restoration contractor for five of those twenty years and earned a bachelor degree in Business Management during that time. I have been providing technical support and training for polyurethane grouts for over fifteen years and have been involved with the International Concrete Repair Institute (ICRI) for a decade.

Social distancing does not have to mean downtime. This is an excellent time to learn about polyurethane chemical grouting. From my home "studio" I bring to your home office demonstrations on crack injection, curtain grouting, and pump operation/maintenance.
