Thaw Underground Pipes

Utility Companies & Construction Crews Use Powerblanket™ to Thaw Frozen Ground & Underground Water Pipes in Cold Winter Weather. Even after spring has arrived, ground will thaw very slowely and can take months to completely thaw out.  To avoid the cost of expensive propane heaters and glycol based heated hoses… companies are turning to Powerblanket for affordable electric outdoor heating equipment. 

Powerblanket is the manufacturer of the only patented heat spreading electric blanket that is both GREEN and comes in avaliable UL/CSA versions.  Also used for heating Road Patch, Curing Concrete, Heating Engines & Equipment, and Warming Barrels, Drums, & Cylinders…  Powerblanket will deliver the heat you need to get the job done FAST!

 

 

 

Concrete Cracks

How to avoid cracks in concrete even in cold winter months.

Under ideal conditions, concrete should cure for 7 days at temperatures between 65-85°F, with humidity levels under 100%. Because of seasonal weather changes, ideal conditions rarely occur naturally.  Insulated and even electric concrete curing blankets can be employed to help maintain concrete temperature during the critical curing process to avoid concrete cracking.

Why Use Powerblanket™ Concrete Curing & Ground Thawing Blankets?

Pouring concrete slabs can be a challenge and cold temperatures can increase the risk that your concrete will not cure properly. Proper concrete curing is a key to a strong, long-lasting concrete slab.  Even the slightest mistake can lead to large cracks and low integrity.

Never pour concrete on frozen ground. Use powerblanket™ concrete curing blankets to thaw the ground and bring the temperature up to at least 65°F. Why? Not only can the ground freeze the concrete from the bottom up, cracking can occur when the ground thaws. Hollow spots under the concrete may also be created – and driving over the hollow spots will create tension which in turn creates cracks.

Likewise, never pour concrete over snow – you’ll simply add unnecessary water to the concrete.

If you’re pouring a foundation slab, temperature control is even more critical. A foundation wall is simply a vertical slab – but it’s exposed on three sides once the forms are pulled. Foundation forms should be protected with powerblanket™ concrete curing blankets for at least three days, depending on weather conditions.

If you remove forms too quickly, your foundation walls will have less protection, especially if you also remove the Powerblanket™ concrete curing blankets. Temperatures below 14°F completely stop the hydration (crystal growing) process.

If the walls are backfilled before proper curing has taken place, the concrete may not be strong enough to withstand the pressure. Once temperatures rise above that point, the chemical reaction resumes, but very slowly. It could take a long time for your foundation walls to gain enough strength to resist the pressure of backfill dirt.

Use Low Slump Concrete

Low slump concrete is hard to work with, but in cold weather it can mean the difference between success and failure. While labor costs can be higher, you’ll have less water bleed problems, and you can place the Powerblanket™ concrete curing blankets on the slab more quickly, reducing the effects of cold weather.

Our testing shows Powerblanket™ to be highly effective at thawing frozen ground and curing concrete during cold winter months.  Achieve higher PSI levels and keep crews working all winter long with the electric outdoor construction Powerblanket™.  They really work… allowing you to move to the next job instead of waiting for your concrete to cure.  You’ll be days & dollars ahead with Powerblanket™.
