Frequently Asked Questions

Why is Bolt-A-Blok construction better?

Bolt-A-Blok construction is stronger and faster and the structures can be installed regardless of weather conditions. Since there is no mortar to cure, the wall system can be built upon as soon as it is finished. Mortar-less block construction is not new. What makes Bolt-A-Blok different from other available systems? The Bolt-A-Blok System is comparable in strength to poured-in-place or pre-cast concrete. Other systems are either dry-stack with no interconnecting support, or with a single rod compressing all the blocks. The patented Bolt-A-Blok System is truly unique.

Do the steel bars create spaces between the blocks?

No. The blocks have a recessed bar groove for the bars to lay in. The patented blocks are made to compensate for the 3⁄8˝ space formerly occupied by mortar, therefore accommodating standard openings for windows, door frames, and vents.

Will rain and water penetrate the wall?

Water will flow through any concrete product unless the concrete is treated. Bolt-A-Blok is excellent for water control in several ways.

  • Because the block is post-tensioned, seams and cracks are less likely to widen with time. Therefore, applied masonry waterproofing coatings will not crack and separate as readily.
  • Water will travel along, and through horizontal surfaces. The bar groove in the top of each block acts as a drip edge, causing the water to be redirected down through the cores rather than through the wall to the inside.
What tools do you need to put a Bolt-A-Blok wall together?

A small hand wrench and a level are all you’ll need to assemble Bolt-A-Blok structures. A ratchet or cordless drill with a ½” socket will enable structures to be assembled even faster.
