SOP 9.2.2 - Integral Solid Surface Sink Drawing and Fabrication Requirements - Cambria

Oct 28, 2026

Upload by Angel

Defines drawing and fabrication requirements for installing an integral solid surface sink onto a Cambria countertop. Limits sink types to approved solid surface only and prohibits hybrid, porcelain, stainless steel, composite granite, and fiberglass-combination sinks. Specifies sink geometry constraints, allowed thicknesses, blending and inside-corner radius options, and required fastener layout coordination. Covers template measurement, CNC tool-path submission, labeling on drawings, sink delivery timing, and FabShop verification steps for production release.

Issued By: Quality Office Page: Page 1 of 5 Objective This document defines drawing requirements and fabrication limitations specific to having an integral solid surface sink placed onto a Cambria countertop piece. Note: Only solid surface sinks can be used for this process. No hybrid, porcelain, stainless steel, composite granite or etc. sinks can be used Note: Sinks that are a combination of solid surface material and fiberglass cannot be used for this process Procedure 1. The sink must be solid surface material that is capable of being blended smooth to the Cambria countertop cutout. a. Radii on the top of the actual sink are not allowed. Sink bowl and sink flange must be perpendicular with no ease or radii. 2. Integral sink are available in 2cm and 3cm thicknesses only. 3. Integral sinks will be adhered to the Cambria countertop at the Cambria FabShop. a. CIA must insure that the countertop and sink combination can be installed without damage being caused to the Cambria, sink or jobsite. 4. The integral sink will also have fasteners (nutserts, sink clips and appropriate hardware) already in place on the fabricated countertop. a. CIA must determine and specify on the submitted fabrication drawing the location of the sink fasteners to eliminate interference with existing cabinetry or supporting structure. A separate layout tab in AutoCAD will be created specifically for this callout. See Figure 1. Issued By: Quality Office Page: Page 2 of 5 Figure 1 i. Refer to SOP 9.3.3 Installation Requirements for Cambria for recommended fastener location. 5. The Cambria countertop cutout and solid surface sink will be blended to each other which may result in subtle impacts to both the sink cutout and the sink. 6. Inside corner radius a. ½” minimum b. Inside corner radii are available in 1/16” increments from 1/2” to 1 7/16”. i. These radii are done by hand-work for an additional fee. In addition, the following statement must be included within the cutout,“Small inside radii, Cambria Hand Polish”. ii. One hour of handwork time will be charged per integral sink with small radii. 7. Available Profiles; a. Tapered i. This polished profile will have a 1/8” top radius and a 3°-6° taper after fabrication. See Figure 2. Issued By: Quality Office Page: Page 3 of 5 Figure 2 8. The solid surface sink must be measured exactly by the CIA and the exact geometry will be submitted at actual size to ensure the countertop or sink are not negatively affected during the fabrication process. The exact geometry will be the digital template that is placedon the Cambria countertop drawing and that the CNC will use as a tool path. 9. The CIA will label the cutouts on the drawings per SOP 9.2.2 with the additional information added to the cutout; “Integral Sink / Cambria to hand polish) . Integral Sink Application must also be stated on the layout. See Figure 3. Issued By: Quality Office Page: Page 4 of 5 Figure 3 10. The actual sink will be provided to the Cambria FabShop once the drawing has been submitted. Note: Job will not be dated until the actual sink arrives at the Cambria FabShop and verification of size has been completed. The following information must clearly label on the sink box and or actual sink. a. Cambria Job \# or CIA PO \# b. CIA information along with piece information sink will mount to. c. Overall size of sink as well as template date and sign off by CIA. 11. The Cambria FabShop will verify the size of the template vs. the actual sink. a. If template is acceptable, job will be moved into production. b. If template is not acceptable; i. CIA can measure the sink at the Cambria FabShop location. Issued By: Quality Office Page: Page 5 of 5 1. Updated sink template will be placed onto the revised Cambria AutoCAD drawings and submitted for approval. ii. Sink can be shipped back to the CIA for measuring. iii. Updated sink template will be placed onto

FAQs

Which sink types are allowed for this process?

Only integral solid surface sinks are allowed. Hybrid, porcelain, stainless steel, composite granite, and sinks combined with fiberglass cannot be used.

What constraints apply to the sink’s top radii and flange geometry?

Radii on the top of the actual sink are not allowed. The sink bowl and sink flange must be perpendicular with no ease or radii.

How are templates and sink size verified before production?

The CIA measures the sink exactly and submits exact geometry as a digital template for the countertop drawing and CNC tool path. The Cambria FabShop verifies template size against the actual sink; production proceeds only if the template is acceptable.
