How To Evaluate Concrete Damage Before Attempting Repairs

Posted by on September 4, 2015 in Uncategorized | Comments Off on How To Evaluate Concrete Damage Before Attempting Repairs

Repairing damaged concrete can be a time-consuming and expensive business, so it’s important to evaluate the damage before proceeding to establish if the project is worth pursuing.  If the damage is severe, it’s probably not going to be a job that you can tackle yourself, and you may need to call in a firm of contractors to carry out any major restoration and repair work. Here are some tips and tricks that you can use to assess a concrete repair job for viability, before you start. Damage evaluation When checking over damaged concrete and deciding if it’s suitable for repair, you must first assess whether the damage is structural or just superficial.  Begin by carrying out a simple visual assessment, making notes as you go. Is the damage widespread or just local?  Single, localised cracks or chips could have occurred as a result of a heavy object being dropped onto the concrete or from plant scraping along it.  Such damage is likely to be purely cosmetic and is easily repaired.  Look carefully to see if the damage extends further into the concrete matrix.  Deeper cracks can still be repaired, but the work required to rectify the damage will be more extensive and costly.  Check to see if the cracks are still active; algal growth and dirt accumulations would indicate that the damage has settled and may have resulted as the result of a one-off incident, rather than being due to an ongoing settlement or subsidence issue.  If you suspect that the cracks may still be moving, keep a diary over a month or so and record measurements of the cracks’ size.  If the damage is ongoing, it could be the result of subsidence and you’ll need to consult a structural engineer to determine the extent of the damage and the remedial works required to correct it. If there is evidence of rust staining coming through cracked or broken concrete steps, this could indicate damage or corrosion to the underlying reinforcing steel structure.  Further investigation by a specialist construction firm will be required to determine just how severe the damage is and how straightforward a repair job would be.  More extensive testing Once you’ve examined the areas of surface damage, it’s a good idea to check for other, less obvious faults in the concrete.  For example, if a newly-laid concrete floor has a crack in its surface, there could also be issues with delamination.  Delamination areas are faults within the concrete caused by air bubbles that have formed while the concrete was ‘going off’.  These areas can weaken the surrounding structure and lead to damage or instability as the concrete ages. The easiest way to test for delamination is to use a hammer.  Gently tap the surface of the concrete with the hammer and listen to the sound.  Solid concrete will resonate with a sharp, ringing sound, whereas delaminated sections will sound hollow and dull.  Mark suspicious areas with spray paint as you go and measure them using a tape measure to give you an idea of the extent of any repairs that are needed. You should now have a clearer idea of the extent and nature of the damage.  If you suspect that there are structural issues, consult a structural engineer or building contractor for further advice.

Things A Heating Service Company Can Offer You

Posted by on August 20, 2015 in Uncategorized | Comments Off on Things A Heating Service Company Can Offer You

A heating service company can diagnose and repair issues that crop up with your central heating, space heater, furnace or water heater. But if you’ve never contracted with one of these companies, you may not know the most common services that they provide, so to help you out, here are some of the things they can handle on your behalf. Water Heater Services — Your water heater regulates the flow of hot water in your bathroom and kitchen, and it also generates the heat for your washing machine and dishwasher. Most water heaters carry at least a 10-year warranty that covers many issues that crop up in the regular operation of the appliance. Heating service company technicians are able to analyse and inspect your water heater when common problems such as a lack of hot water occur. One of the main reasons that a water heater stops warming water is that the heating element inside the tank has malfunctioned. Another common issue is a knocking sound inside the tank that is the result of hard deposits that have formed in the tank over a long period of time. A heating service technician may have to flush your entire tank to resolve this problem and install a new anode rod, a component that protects the inside of your tank from rust. Furnace Services — Furnaces tend to stop working when you need them most, which is usually during the winter. Dirty filters are one of the most common issues with a furnace, but other issues that a heating technician can fix include bearings that are worn out, pilot lights that won’t ignite or won’t stay lit, a malfunctioning thermostat, which controls the level of heat in your home, and a compromised fault limit switch that regulates the blower function. Inspection/Maintenance/Tune-Up — To keep your water heater and furnace at peak efficiency, a heating service technician can perform an annual inspection to determine if there are any potential issues that should be handled before they become major repairs. For example, heating service technicians will often test the carbon monoxide levels and natural gas level in your home to ensure there are no toxic gases flowing from your heater or furnace because of a leak. They can also inspect your exhaust system to ensure proper ventilation, and they can recommend and install insulation on your water heater pipes to make the heating process more energy efficient. If you have specific questions about heating services, talk with a contractor from a company like Guy Hyde Gasfitting & Appliance...
