UNIQUE’s Tips for Concrete Pool Repair

Posted on:
concrete pool repair

Concrete pools are extremely durable and long lasting. With proper care and maintenance, they can last many years without any issues at all. However, it is inevitable that over time there can be damage, such as cracking, which may require an underwater concrete pool patch. There are two main types of cracking when it comes to an underwater concrete pool, which are:

How Cold Mix Changed the Way Canada Repairs Potholes

Posted on:

Successfully repairing potholes requires more than simply filling the damage using pothole filler and hoping your repair holds up. Cities, municipalities, and homeowners alike must research pavement repair solutions and gather information about each product to find the right fit for their pothole repair needs.

Niagara Falls is one such location. The municipality wanted a way to relieve the pothole damage, daily wear-and-tear, and general road stress potholes were having on cars in its community. Niagara Falls started leveraging Unique Paving Materials’ cold mix solution. According to CHCH News, cold mix is a new product in Canada this winter and has been producing positive results on the roads.

Control Pothole Cost

Posted on:

Agencies have three main costs for pothole patching: material, labor and equipment.

The cost of purchasing material is one of the most common focus points, but the least significant factor to the overall patching operation.  (Strategic Highway Research Program, SHRP-H- 348).Manuals of Practice SHRP

Stay-in-place capability will significantly impact the frequency of re-repairs and overall maintenance costs; replacing a pothole just once doubles the cost. Some potholes are re-repaired on a weekly basis.

Anyone can combine asphalt with rock, and any combination can be marketed as equal.  Design for permanent performance, or design for temporary performance ­­– producer’s/buyer’s choice. Temporary designs will not perform like UPM. The most common position is “Cold mix is cold mix, equivalent to UPM “.  This is far from the truth and unsupported by analysis or controlled performance testing.

The secret is the process: controlling aggregate, asphalt, additives and manufacturing.  An asphalt film on the rock makes the rock black; having the optimum film makes it permanent.  Surface area, one of the most critical parameters, determines the amount of asphalt and additive to achieve optimum rock to rock cohesion and cold mix to pothole wall adhesion.

Consistent performance can only be achieved through testing, design and control.  Like HMA, the better the design and QC the longer lasting the road.

Installation contributes to overall performance, therefore, installation methods and training should be a incorporates into every maintenance program.

Those interested in lowering total maintenance costs should approach pothole repair as permanent and not as a temporary fix. Eliminating reappearing pothole repairs creates an opportunity to repair more potholes with identical resources resulting in increased service to the community.

UNIQUE rejects more than 50% of aggregates submitted for UPM production. UNIQUE applies the optimum film (asphalt and performance additives) during production. UPM is designed to out perform any competitive cold mix.
