Gravity Crack Injection

UPDATE: See: Concrete Mender™ Full Depth Crack Injection

Roadware 10 Minute Concrete Mender™ is an excellent choice for repairing full depth concrete slab cracks. The very low viscosity of less than 8 cps and the exclusive Microdoweling™ penetration properties of the material allow it to flow deep into cracks. The procedure below illustrates Microdoweling™ in action.  The Concrete Mender will restore aggregate interlock and will allow dynamic load transfer under heavy traffic. The expense and mess of pressure injection with epoxy can be avoided.Here is a parking deck project located in the North Eastern United States. Hairline cracks run 9-12 inches deep through the deck slab. The contractor drilled 1 1/2 inch holes, 2-3 inches deep into the hairline cracks approximately every 18 inches. Inspection from the floor below reveals full penetration without pumps or ports. Engineers tell us that Roadware Microdoweling™ is quicker and more cost effective than epoxy injection.  The results speak for themselves.

concrete mender, Concrete Repair

Concrete slab under wood floor crack repair.

Today I received several photographs of a large crack that developed under a hardwood floor in a slab-on-grade application. The crack buckled the hardwood flooring. The home owner consulted several contractors and engineers to solve the problem. No cost-effective solution could be found until Roadware contractor, Clay Kenny, (Manderville, Lousiana) arrived on the scene.

Using Roadware 10 Minute Concrete Mender™ and silica sand, Clay repaired the crack to full depth and re-bonded the slabs back together using Roadware’s Microdoweling™technology.

The repairs cured in just 10 minutes and Clay was on and off the job in just 3 hours. The home owner was amazed. Clay and 10 Minute Concrete Mender™ did what couldn’t be done. The hard wood flooring was re-installed and the floor was put back in service faster then anyone could imagine. This repair took nine 600ml cartridges of #80300 Roadware 10 Minute Concrete Mender™ and a 40 lbs bag of silica sand to complete. The Concrete Mender™ turned a flooring disaster into an opportunity.
Anyone in the concrete business knows that concrete can be unpredictable and even a well thought-out project can develop cracks. Some are minor, and some can cause a real problem. Roadware 10 Minute Concrete Mender™ can help make the problems manageable.
