FAQs

How effective are concrete blankets? ›

Concrete blankets are incredibly effective at keeping the material warm during its curing process. In fact, these blankets can keep concrete at an ideal temperature even when the weather drops below 20°F. And since the setting process occurs so quickly, you'll usually only need to rent one out for a couple of days.

Fresh concrete frozen during the first 24 hours can lose 50% of its potential 28 day strength! Use insulation blankets or heated enclosures to maintain concrete temperatures above 50° degrees Fahrenheit for three to seven days.

The drawback on blanketing concrete is that the insulated blankets keep all moisture from the curing process under the blanket, (really good for hard concrete) but this moisture then pools and follows the crinkles in the insulated blanket and can cause some unsightly marking, that becomes a permanent part of the ...

Although the blankets can be reused, they get dirty, are hard to store, and are difficult to clean.

Insulating tarps help regulate temperature during construction projects, which is essential to maintaining the curing process and final strength of concrete. Tarps are often one of the first solutions considered when facing cold weather conditions.

The burlap side of the blanket faces down towards the concrete. Burlap is made of natural moisture absorbing fibers and it basically holds in the moisture. The white coated poly fabric faces up reflecting sunlight and intense heat rays. This curing method allows for a smoother, harder and more durable concrete surface.

For it to set correctly, you must protect fresh concrete from freezing during the first 24 hours. If it freezes, it will lose much of its strength. However, with proper safety measures and planning, you can pour concrete successfully even in cold weather conditions.

For freshly poured concrete to reach its full strength the curing process must be allowed to continue for at least 28 days. If the concrete freezes during the curing process the curing will stop.

The ideal time to pour concrete at night is after sunset or after 8 p.m, to midnight or before 10 a.m, to avoid the hottest time of the day. Maintaining the ideal temperature will provide a good curing process for concrete, so pouring concrete at night is recommended, especially in high-temperature areas.

These ground thawing blankets are perfect for curing concrete, protecting slabs of concrete, curing newly laid brick or block walls, and thawing any ground surface for landscaping jobs.

Does concrete sag over time? ›

Unlike homes with basem*nts or crawl spaces, a slab floor is solid concrete with no structural wood flooring system. For homes with this type of floor, soft soil or bad compaction is almost always the culprit. Once the soil is compromised, the slab will shift, and this creates the sagging or sinking effect.

The dark gray discoloration is caused by varying degrees of hydration of the cement in the concrete, caused by the varying moisture contents in the localized areas of the total concrete.

Instructions: Lay out BurLene® Blankets (burlap side down), lapping 6" on top of slab, and allowing sufficient lap over edge, to seal-in. Fog spraying concrete and/or pre-wetting burlap side of BurLene® may be helpful in most applications.

Bonding Agents. So, concrete can't stick to very much on its own and it needs a little help to adhere to old layers of concrete. That's where bonding agents come in. As well as allowing old and new concrete to adhere, the bonding agents also help to protect the combined layers of concrete.

In theory, yes, pouring concrete over concrete is possible. Typically people want to pour concrete over old concrete because their existing surface is slightly damaged, faded, or just outdated.

Concrete curing covers help maintain a certain level of heat and protect the concrete from colder temperatures. The covers can heat up to 110°F and trap moisture and heat, which helps accelerate the curing process.

The R-value of fiberglass blanket insulation depends on its thickness. It has an R–value of approximately R-2.9 to R-3.8 per inch of thickness. To give you a better idea, insulation that is 3 ½ inches thick has an R-value of about 11, and insulation that is 12 inches thick has an R-value of about 38.

These concrete curing blankets, also referred to as insulated tarps, feature a poly black exterior to provide maximum temperature gain from the solar heat. Our concrete curing blankets are available in a range of different R values up to 7.8.
