Concrete

Concrete in the kitchen! It's new and different--a hot new countertop, sink, backsplash, floor, and wall material--it's not just for foundations anymore! At 1 ½" thick, the cost is similar to granite and marble at approximately $65-100 per sq. foot (including local delivery and installation). The estimated cost for a concrete sink can range from $600-$2000. Fabrication for special edges, curves, aprons, and dropped edges will cost extra. Deep colors and/or mixing various materials or objects into the concrete can also drive up the cost. There are different types of finishes available including troweled, textured, and smooth pressed. Seams between concrete slabs or panels can be filled with either a matching or contrasting grout.

Concrete countertops are made to order by fabricators at their shop. Pigments are added to concrete before it is poured into custom molds (made from a template of your exact kitchen countertop measurements). Galvanized wire mesh is usually inserted into the concrete for reinforcement. Holes can be drilled for faucets and cut-outs can be made for sinks and cooktops. If you are planning a cantilevered countertop beyond 10 inches you must have additional support.

Some fabricators will pre-cast oversized slabs (up to 11 ft. long) to be cut on-site. Either way, it is recommended that you request a sample of the color before the actual countertops are made. Concrete is shipped locally or cross-country in plywood crates--the further the distance the higher the risk of being damaged. When choosing a fabricator, make sure he or she comes with recommendations and proven experience--because if concrete is improperly poured or installed, spalling or warping can occur up to 6 months later.

Concrete is extremely durable and with proper care it will last a lifetime. It is a porous material that needs sealing to protect its surface from staining and moisture. Some of the sealing products that can be used include silicon sealers, acrylic topcoats, and butcher's wax. No matter how it is sealed, it is important to clean up spills as soon as possible. You should also avoid cutting food on the surface. Hot pots (up to 330° F) may be briefly set down but don't leave it there for a long time. Cracks and chips can be repaired by a combination of concrete filler, sanding, and reapplying a surface sealant.
