how to repair a pipeline under a house?

Pipe lining represents a revolutionary technique that offers a durable alternative to repairing damaged pipes without requiring their complete replacement. This method involves inserting a liner made of polymer resin inside existing pipes. This intervention strengthens the conduits, repairs cracks and leaks, while protecting against corrosion. Suitable for various drainage networks, including wastewater, sewage, and stormwater, pipe lining is a versatile solution.

This article aims to guide you on how to identify the causes of pipe problems, present trenchless repair methods, and examine the factors to consider before choosing a repair technique. You will discover the advantages of pipe lining, a trenchless rehabilitation method that is fast, cost-effective, and environmentally friendly.

Identify the cause of the pipe problem

The essential first step before opting for trenchless pipe repair is to precisely identify the origin of the problem. The cause and severity of the damage directly influence the choice of the most suitable repair technique. To do this, several key steps must be followed:

Camera inspection

Camera inspection, a quick and non-destructive method, involves using a waterproof camera maneuvered through the pipe with a flexible cable. This technique provides a detailed view of the inside of the pipe, allowing precise location of damage and identification of its causes. Thanks to it, it is possible to accurately diagnose the problem without requiring excavation work.

Detection of leaks and blockages

The detection of leaks and blockages uses special tools, such as acoustic detectors, tracer gases, or dyes, to identify sections of the pipe that are leaking or blocked. This step is crucial to assess the severity of the problem and adequately plan the repair.

Assessment of the extent of damage

The assessment of the extent of damage relies on data collected through camera inspection and the detection of leaks and blockages. This analysis helps determine the nature and severity of the damage, whether it involves cracks, infiltrated roots, failing joints, corrosion, or pipe collapse. It allows for selecting the most suitable repair technique, taking into account the specific characteristics of the pipe concerned, such as its diameter, length, and configuration.

Methods to repair a pipeline without excavation

Identifying the pipeline problem is the first step, closely followed by choosing the appropriate repair method. To repair a pipeline without digging, several options exist. These options are not only quick and economical but also environmentally friendly as they avoid damaging surrounding infrastructure.

Below, discover the main trenchless pipeline repair methods:

Pipeline lining

Lining is a frequently used approach to repair a pipeline without excavation. It involves inserting a polymer resin liner inside the damaged pipeline. This liner conforms to the shape of the original pipe and hardens within a few hours, thus creating a new pipeline inside the old one. This method addresses issues such as cracks, leaks, intrusive roots, and defective joints. It also reinforces the pipeline structure, improves its watertightness, and protects it against corrosion. Lining is suitable for all types of drainage networks.

Spot Repair

This method involves locally repairing the pipeline by applying a fiberglass sleeve impregnated with epoxy resin over the damaged area. This sleeve attaches to the pipe and repairs it durably. Ideal for minor damage such as cracks or holes, spot repair avoids full pipeline replacement, significantly reducing costs and intervention times.

Curing and high-pressure cleaning

These techniques aim to repair a pipeline without digging by removing blockages and deposits that hinder flow and water quality. Curing uses a mechanical tool to remove buildup, while high-pressure cleaning uses a powerful water jet up to 400 bars to dislodge debris. These methods help restore the pipeline's capacity, prevent blockages and bad odors, and thus extend the pipeline's lifespan.

Important considerations before choosing a repair method

Identifying the cause of the pipeline problem and evaluating trenchless repair options is crucial. Before deciding, it is important to consider essential criteria to find the most appropriate solution. Here are the major considerations to take into account:

Cost and available budget

The cost varies considerably depending on the diameter, length, shape, condition of the pipeline, and the selected repair method. Trenchless repairs tend to be less expensive compared to traditional approaches, allowing savings on digging, demolition, rehabilitation, and debris management costs.

Prices can range from 100 to 500 euros per linear meter, varying according to the technique used. It is crucial to compare offers from several providers to find one that fits your budget and meets your expectations.

Durability and warranty of repairs

The longevity of a trenchless repair depends on the quality of materials, the expertise of the technician in charge, and regular maintenance. Processes like lining reinforce the pipeline's strength, increase its watertightness, and protect it from corrosion.

A pipeline repaired using these methods can last up to 50 years. It is therefore essential to inquire about the guarantees provided by the service provider and to strictly follow maintenance recommendations.

Impact on property and daily life

Trenchless repairs have minimal impact on the property and daily life, avoiding the inconvenience of excavation work. Fast, discreet, and eco-friendly, these techniques do not damage the nearby environment such as walls, sidewalks, or trees and generate no noise, dust, or debris.

They do not stop the use of the pipeline during the work, do not deteriorate water quality, and exclude complex administrative procedures. Ideal under a dwelling, they allow repairs without disturbing the residents' comfort.
