Our full service commercial plumbers at LA Metro Plumbing repair or replace sewer pipes to correct a number of problems. Commercial building have the responsibility of maintaining the sewer lines connecting their premises to the city’s sewer main. In general, this means the lines that connect at the curb or sidewalk. If drain and sewer pipes are left in disrepair, it could cause an environmental hazard via flooding and groundwater contamination. LA Metro Plumbing offers sewer line repair, sewer line replacement, and sewer line installation to correct a number of problems commonly associated with sewer lines, including:
- Broken, cracked, offset or collapsed pipes – Sometimes settling, cold temperatures, shifting of soil, and other natural occurrences cause such damages.
- Blockage – The presence of a foreign object or buildup of grease sometimes restrict or block the flow and/or cleaning of a sewer line.
- Corrosion – the sewer pipe has deteriorated and/or broken, causing sections of the pipe to collapse and restrict flow.
- Leaking joints – When seals between pipes are broken, water escapes into the areas surrounding the pipe.
- Bellied pipe – If ground and soil conditions alter in a way that causes the sewer pipe to sink, it creates a valley prone to collecting paper and waste.
- Roots in sewer line- Tree or shrub roots often seek out water sources, which means they find their way through or into sewer pipes, causing damage.
- Off-grade pipe – Existing pipes may have been substandard or made of outdated material that may have deteriorated or corroded.
Traditional Repair Method
The most common way of performing sewer line repairs is using the “open cut” or “trench” method to gain access to the area surrounding the damaged portion of the pipe. A backhoe may be used to open and refill the work area. As you can imagine, this is an extensive process.
Trenchless Repair Methods
Trenchless repair methods cause less damage than traditional sewer line repair techniques. LA Metro Plumbing offers trenchless repair sewer line replacement as a matter of preventing extensive costs due to breaking apart sidewalks and parking lots, as well as securing hazardous or disruptive open trenches.
LA Metro Plumbing is proud to use trenchless technology for sewer line repair and sewer line replacement because it has almost no impact to the surrounding environmental landscape-and it’s cost-effective for our customers.
Anyone who has had to deal with an incident involving a burst pipe knows how messy and expensive repair can be. LA Metro Plumbing uses a specific technique of making small access holes where the damaged underground pipe starts and ends. Using the existing broken sewer pipe as a guide, our hydraulic pipe bursting machine will pull a full-sized replacement pipe through the old path while breaking up the damaged pipe at the same time. The new sewer pipe is highly resistant to leaks and root intrusion, and it comes with a lengthier life expectancy. The process is completed faster than open cut methods and can replace cast iron, clay, terra cotta, PVC, and concrete pipes. The process even allows for upsizing lines and there is less risk of damage to utilities in close proximity to damaged pipes.
Pipe bursting techniques can be implemented in the following situations:
- Sewer laterals
- Under slabs and floors
- Water mains
- Irrigation lines
- In tight spaces
- Manhole to manhole
- Under roadways, driveways, and parking lots
- Historical sites and locations where preservation is required
- Where trenches are too dangerous
LA Metro Plumbing also offers pipe relining services. This process involves creating a “pipe within a pipe” in order to repair damaged sewer pipes to full function and flow. Epoxy relining materials are inserted and then mold to the inside of the existing pipe to create a smooth and tough new inner wall.
In many instances, pipe relining can be performed through a building’s sewer clean-out access and the process usually requires very little digging. This process is typically elected when repairing root-damaged or rusted pipes; sealing cracks and holes; filling in missing pipe and seal joint connections underground; in roof drain pipes and storm lines; and under concrete.
A felt-lined flexible tube (the liner) is first filled with an epoxy and resin mixture, then inserted into one end of the damaged pipe. After that, a “bladder” is inserted and inflated to press and hold the new lining against the sides of the existing pipe. The bladder is left in place for four to six hours until the lining has cured and adhered to the old pipe. The resulting pipe is seamless and durable. The technician will then perform a video camera inspection to ensure that the pipe is draining properly and is free of obstructions. All materials used in the relining process are non-hazardous.
There are several strong benefits of choosing the pipe relining process:
- Minimal damage to property
- No risk of damage to nearby existing pipes
- Reduced downtime during repairs
- Lengthy life-expectancy
- Non-hazardous materials will not harm the environment
- Relined pipe cannot be penetrated by tree roots
- Guaranteed materials and workmanship
