Large Cast A Seal in concrete monobendCast-in seals for precast structures are unique for a lot of reasons and you’re here reading this because you have questions about the seal, right?

So let us fill you in on 5 misconceptions you might have.

Complicated Seal Costs More

Because the seal is cast into the structure, you might think it’s a more complicated process that costs you more. But in reality it does not because it saves you time, money and energy in the field because you’re not coring a hole or taking the extra time to insert a boot. The simplicity of the cast-in seal allows you greater flexibility (no pun intended) in your day-to-day business operations.

Boot Can Get Damaged

You might be envisioning this rubber connector sticking out the side of your precast structure and now it’s going to be transported on a truck where it will surely get damaged. But that’s not possible because the design of the connector allows it to be folded inward for transport and then once in the field, it simply can be unfolded to protrude from the structure and easily attached to the pipe with our supplied clamps.

Cast-In Seals Prevent Deflection

Our Cast-A-Seals are designed like our boot-type connectors and this accommodates pipe deflection without losing the seal. The large key-lock assures a watertight seal between the connector and the precast structure.

Requires Expensive Hole Formers

Tooling for casting is available for many sizes or you can easily fabricate them yourself from the host pipe or rolled steel rings.

It’s Only for Concrete Pipe

You might think these connectors are only for concrete pipe, because we’re talking about precast concrete structures. But that’s certainly not the case. You can use cast-a-seal connectors for PVC, ductile iron and concrete pipe. Available for pipe sizes from 1-1/4” to 72” (32-1800mm) we’re certain we have the right connector for your needs.

Box culvert being lowered down into a ditch with other concrete boxes

The alternative to precast concrete pipe is the building block of underground infrastructure called the box culvert. They are essentially the Lego of modern precast structures and simply snap together for easy installation. As with any product that utilizes a joint that could move, you inherently run the risk of infiltration or exfiltration. Therefore you […]

Looking down hole at large concrete pipe

Microtunneling is becoming one of the most common forms of underground construction to help mitigate disruption of the area where the project is taking place. And this year Press-Seal’s customer, Northern Concrete Pipe, was able to assist in achieving a new U.S. record for a single bore of pipe that stretches nearly ¾ of a […]

Boot connectors come in a wide range of sizes and types for different applications, but one thing that remains the same are take-up clamps. These take-up clamps are used to secure the boot connector to the pipe using a 304 stainless steel clamp. In today’s episode of Press-Seal U, territory manager Sean Fowler shows us […]

If you had to call the fire department and they ran out of water, what do you think the odds are of them saving your property or the lives of you and your family? In many rural settings across the States and Canada, these properties are at a much higher risk for a greater loss […]

A rubber pipe gasket is used for sealing underground collection systems and structures including the most common ones: Round Pipe Arch and Elliptical Pipes Box Culverts Jacking and Micro tunneling When considering which pipe gasket is right for your type of structure or application, you’ll find many varieties to choose from. So let’s start off […]
