Eighty percent of crop yield loss within a field and within years can often be attributed to variable moisture availability, both too little and too much. Excess moisture also plays havoc with machinery operations and farm efficiency. By improving surface drainage and promoting more uniform infiltration, Optimum Surface Landforming has shown to provide a range of profit boosting benefits at a relatively low cost per hectare resulting in a high Return On Investment (ROI).

Highways and driveways both heavily depend on asphalt pavement. The performance and longevity of the surface can be significantly impacted by the caliber of the paving job. Because of this, receiving the right advice from Oakville asphalt paving professionals is crucial to guaranteeing a smooth, long-lasting asphalt surface that improves both beauty and functionality.

The answer is NO. Surface water is not covered due to policy flood insurance exclusions … but just what is “surface water”. We recently helped an insured who had presented a water claim that was denied due to the “Surface Water Exclusion”. The loss arose out of a human error which allowed irrigation water to run longer than it should have and a basement of an upscale home filed up with water causing some serious damage. The insurance company’s response was to write a letter regarding policy “exclusions”. The policy contains the following exclusions:
