Concrete Guide
Sidewalks and Driveways
Your driveway, sidewalks and patios are steel re-enforced. The front sidewalk may be supported with steel brackets underneath to ensure that it will not settle, even if the ground does.
Driveways are designed for the use of passenger cars and light duty vehicles. Heavy trucks will cause damage and therefore should be kept off the driveway.
In winter months, salt that is applied to city streets may affect the surface of the driveway. To reduce surface damage from salt, remove any slush accumulation on the concrete. Commercial concrete sealers are available that may help to reduce damage. It is recommended that you seal your driveway every year. During the winter months, when driveways and sidewalks cannot be installed, Truman will supply you with a temporary sidewalk consisting of sidewalk blocks. When temperatures and ground conditions enable us to pour concrete, we will put in place your driveway and sidewalk. Frost penetration in winter can cause vertical movement of sidewalk and driveway slabs, affecting surface drainage. This condition will correct itself with the return of winter.
Basement Walls
Basement walls are subjected to many stresses. The base of the wall, being well below grade, maintains a fairly uniform temperature; whereas the portion above grade is subjected to a wide range of seasonal temperature variations. Basement walls are damp proofed on the exterior, and insulated and polyed on the interior. A common misconception is that basement walls are waterproof.
Basement Floors
The basement floor is considered a non-structural component. The nature of concrete is such that some surface pitting and superficial cracking will occur. This is normal and little can be done to prevent it. Should you choose to paint the floor, be sure to use a product recommended for that purpose. Among other things, it should be alkaline resistant and of a type that would permit continuing curing of a new poured floor
Garage Floors
The garage floor is reinforced with steel to support passenger vehicle weight. Once the concrete has cured totally, you may wish to treat it with concrete sealer made specifically for this purpose. Consult your paint dealer for the recommendation of a suitable product.
Precast Steps & Platforms
Precast steps and platforms are pre-manufactured. They are then delivered and placed on site on steel brackets, which are then fastened to the foundation wall.
Concrete FAQs
Question: What is the white powder that is appearing on some areas of the concrete floor and walls?
Answer: The white powder, known as efflorescence, is caused by salts in the concrete mix that are brought to the surface as moisture evaporates during the curing process. This is a normal occurrence and leaves a harmless salt deposit that can easily be brushed off. Efflorescence does not impact the strength or performance of the concrete and typically stops forming once the curing process is complete. Regular sweeping or light cleaning can help remove the deposits as they appear.
Question: What are the yellow stains on my driveway and concrete floors?
Answer: The yellow stains on new concrete are caused by the curing compound applied to help the concrete properly harden and strengthen. These stains are temporary and will gradually fade over time as the compound breaks down. There’s no need for concern, as this is a normal part of the curing process and does not affect the durability or integrity of the concrete.
Question: Why are cracks developing in the driveway, basement floor, garage floor, and sidewalk? Should I be concerned?
Answer: Cracks in concrete are a normal occurrence and typically not a cause for concern, as they are not structural. These cracks are often the result of natural shrinkage in the concrete or seasonal changes in temperature and precipitation. Hairline cracks are generally accepted within industry standards. However, if you notice more significant cracking—such as basement or garage floor cracks of 4mm or greater, or driveway cracks of 6mm or greater—these may require attention. Such cracks can be repaired if reported within the one-year warranty period, so be sure to schedule a service appointment if needed.
Question: Should I be concerned about cracks in the basement walls?
Answer: Minor cracks in the basement walls are quite common and generally not a cause for concern. These small cracks often result from the natural expansion and contraction of materials due to temperature fluctuations. However, if you notice any cracks that are allowing water to seep into the basement, please contact Truman’s Warranty Department immediately so we can assess and address the issue promptly.
Question: Why isn’t my exposed aggregate driveway as shiny as it was when we first moved in?
Answer: Your exposed aggregate driveway was sealed before occupancy to protect the concrete and enhance its appearance. Over time, the sealer naturally fades due to weather and general wear. To maintain the shine and protect the surface, it’s recommended to reapply the sealer at least once a year after possession.
Question: Why is my driveway having small pieces flake off (spalling)?
Answer: Spalling occurs when the surface of the driveway begins to deteriorate, often due to exposure to harsh conditions or improper maintenance. Common causes include the use of de-icing salts or road salts, which can break down the finish over time. To prevent further damage, it’s important to keep your driveway clean and avoid using abrasive materials or chemicals. Regular maintenance and prompt cleaning of any debris will help preserve the finish and prolong the life of your driveway.
