Self Levelling Concrete | Self Compacting Concrete

The product cost of high performance concrete can be more than offset by significant productivity and performance gains. Because Evolution™ can flow from a single point (note: on large pours more than one point may be required), is self-levelling, selfcompacting and eliminates the need to hire expensive vibration equipment, the cost of placing the concrete can be significantly reduced.

The Disadvantages of Pouring Concrete Over Existing Concrete Slab

Jul 17, 2017 · A well-poured concrete slab with a deep, sturdy foundation can last for 30 to 40 years. Pouring concrete over old concrete instead of directly over a new gravel foundation limits your ability to maximize the slab's lifespan. The condition of the existing slab is the primary factor that determines how long the new concrete will last.
