PRE-BENCHING – SAVE TIME & MONEY IN THE FIELD
Image of a pre-benched maintenance hole.

Benching precast maintenance holes in the field is a dying art form, which can be very time consuming, labour-intensive, and costly. It can also lead to less precise work and damage to product. That’s if you can find trained staff to perform benching in the field!

Concast is pleased to offer pre-benching for sanitary and storm maintenance holes. We have perfected the process in-house, utilizing state-of-the-art machinery and a trained team of professionals. Using EPS, we can get the variance down to approximately 2mm, keeping measurements accurate.

Why pre-benching?

Pre-benching is done to create a channel within the maintenance hole to guide the flow of water/sediment out of the pipe. We can do this by creating a through and through pre-benched channel (straight through the maintenance hole) or a curved/angled channel to direct the flow.

What are the benefits?

There are a few benefits to choosing this method over traditional field-benching:
- Saves time in the field, keeping your project on time
- Saves on cost, keeping your project on budget
- Done in-house, ensuring precision and a smooth finish
What sizes are available?

We can work with the following diameter maintenance holes:
- 1200mm diameter
  - Including 600Ø maximum pipe size for through and through benchingIncluding 450Ø maximum pipe size for curved/angled benching – with 2x 450Ø pipe maximum angled.
  - We can have multiple benching channels for smaller diameter pipe sizes
- 1500mm diameter
  - Including 825Ø maximum pipe size through and through benchingIncluding 600Ø maximum pipe size for curved/angled benching – with 2x 600Ø pipe maximum angled
  - We can have multiple benching channels for smaller diameter pipe sizes
NEW: Add our HDPE liner for added protection!

Interested in giving your project an additional layer of protection? Why not add our HDPE liner to protect from corrosive gases and liquids. This is especially valuable in sanitary management systems, where these issues can be prevalent.

SPREAD THE WORD: CONCAST MANUFACTURES DROP STRUCTURES
You heard it here first! Concast now manufactures drop structures, saving you time and money in the field!

Why Drop Structures?

Drop structures are required when you have an inlet sewer that is significantly higher than the outlet through a maintenance hole, and you need to bring the flow down to the elevation of the outlet. They can be built in the field; however, they are very costly and labour intensive. Our precast drop structures require no additional time or effort from the customer, keeping your project completion on time.

What are the Benefits?
- Saves you time and money in the field
- Factory manufactured vs. field manufactured
- Controlled environment ensures the highest quality standards are met
- Quick and easy to install – simplifies maintenance hole backfilling
- Monolithic casts = better quality
What sizes are available?

Our form is capable of the following specifications:
- Riser diameter of 1219mm
- Monobase height of 914mm and 1219mm
- Middle riser and top riser heights of 914mm to 1828mm, in 150mm increments
- PVC sizes
  - 150mm Tee and Wye
  - 200mm Tee and Wye
  - 250mmx200mm Wye
  - 250mmx250mm Tee
  - 300mmx250mm Tee
