Septic System Installation
We design and install conventional, tertiary, and Eco-Flo septic systems tailored to local soil conditions. Our process includes site assessment, regulatory compliance, and precision installation to ensure long-term functionality. Clients benefit from our expertise in challenging environments like hard clay or rocky terrain.
Eco-Flo Septic Systems
Eco-Flo systems provide advanced wastewater treatment for properties with poor soil permeability. We are certified to install these tertiary systems, which meet Ontario Building Code requirements while preserving landscaping features like trees and pools.
Septic Repair Services
Our team diagnoses and repairs failing septic systems, including tank replacement and header line restoration. We prioritize cost-effective solutions while ensuring compliance with current regulations, even for older properties with non-standard setups.
Soil Assessment
We conduct detailed soil analyses to determine optimal septic system design. This includes percolation testing and matrix evaluation, ensuring solutions like raised filter beds or tertiary systems are implemented where conventional systems are unsuitable.
Filter Bed Installation
We install durable filter beds for residential and commercial properties, using engineered designs to handle high water tables or shallow bedrock. Our systems incorporate durable materials and strategic drainage to prevent biomat buildup and system failure.
