Today the architectural surface treatment industry supplies a broad assortment of concrete molds that provide usability and function, but design expectations continue to evolve. Architects and builders are answering the call of the public and private sector to design bridges, retaining walls, sound barriers and buildings with positive aesthetic

Can Power Washing Damage Concrete? | ABC Blog

The quick answer is yes, power washing can degrade a concrete surface. You can notice visible damage from water pressure at the level at which even light-duty power washers can operate. Therefore, if you aren't careful, you can cause irreversible damage to your driveway or patio. Also, some concrete is weaker than others, making some areas

Damp-Proofing Concrete Floors (Refurbishment

Damp Floor Treatment. Damp rising through concrete floor slabs is fairly common, causing damp issues on carpets and floor coverings, warping wooden floors and increasing the likelihood of low-level mould growth. The damp-proof membranes used during construction of concrete floors are often thin, and can easily become torn before they are laid

Pre-Treating Concrete Before Cleaning Your Driveway

A post-treatment will reduce any visible striping from your surface cleaner and will kill off any remaining bacteria left on the concrete. A post-treatment will also help keep your driveway cleaner for a longer period compared to only using a pressure washer to clean. Step 6: Enjoy your clean driveway!

Chloride Penetration through Cracks in High-Performance

For plain concrete and surface treated concrete, the critical crack size that can be healed by surface treatment systems is examined. Cracks smaller than this critical crack size are considered not to have a significant influence on the rate of chloride transport inwards, while chloride penetration does proceed faster above the critical crack size.

Performance of Concrete Bridge Deck Surface Treatments

The purpose of this research was to identify the types of surface treatments available for use on concrete bridge decks and to determine which materials are most capable of providing long-term protection from contamination by chloride ions. The products addressed in this report primarily include urethanes, silicon-based sealers, and epoxies. An extensive literature review was conducted to

What to Do After Your Concrete Is Poured | Razorback Concrete

Finishing concrete properly is a skill that is only acquired through experience, so you may try practicing pouring concrete on smaller projects before tackling a patio or a driveway. First, you should smooth your concrete out with a tool called a screed, which is essentially a board you run across your concrete to level out the surface.

Heavyweight Concrete Blocks Are Semi-Permeable - Concrete blocks (CMUs) have larger pores than poured concrete and only thin walls (about 1-1/4-inch) next to their hollow cores (3.2/1.25 = 2.6 perms). Materials with permeance of 1 to 10 perms are classified as "semi-permeable," although the permeance of concrete blocks varies widely.
